[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4 The utility model provides an embodiment: a clamp for welding automobile accessories, comprising a support table 1, the support table 1 can support the automobile accessories to keep them horizontal, the upper end of the support table 1 is elastically connected with a ramp block 7 through a spring 8, the ramp block 7 is L-shaped, and the upper end passes through the support table 1 for convenient sliding and releasing the limit, one end of the spring 8 is fixedly connected to the outside of the side end of the ramp block 7, the upper end of the lower part of the ramp block 7 is a ramp, which can be squeezed and slide into the support table 1 to facilitate the sliding of the connecting block 5, the other end of the spring 8 is fixedly connected to the inside of the upper side end of the support table 1, the spring 8 keeps the state of squeezing the ramp block 7, the lower part of the ramp block 7 is slidably connected with the connecting block 5, the connecting block 5 is U-shaped, and can be restricted by the ramp block 7 from sliding up and sliding horizontally, the outer part of the connecting block 5 is slidably connected to the inside of the side end of the support table 1, the connecting block 5 is restricted by the ramp block 7 and the support table 1 and can only be kept relatively fixed, so that the base 4 is fixed and will not slide out, and the side of the connecting block 5 is fixedly connected with the base 4.

[0032] Reference Figure 2-Figure 4The base 4 is internally slidably connected with a T-block 13, and the T-block 13 limits the sliding plate 3 to only slide relatively horizontally within a fixed distance. The upper end of the T-block 13 is fixedly connected with the sliding plate 3, and the upper part of the sliding plate 3 can fix the clamping device to clamp the automobile accessories, and the lower part of the sliding plate 3 contacts the top of the base 4, and the sliding plate 3 can be supported by the base 4 to remain stable. The internal sliding connection of the T-block 13 is provided with a clamping block 6, and the clamping block 6 can clamp the T-block 13 so that it cannot slide and is fixed relative to the base 4, so that the clamping device clamps the accessories, and the outer sliding connection of the clamping block 6 is internally connected to the lower end of the base 4, and the lower part of the clamping block 6 is fixedly connected with a rotating circle 2, and the rotating circle 2 limits the clamping block 6 to rotate only relative to the center of the supporting table 1, and the middle of the rotating circle 2 is fixedly connected with a cross 9, and the cross 9 limits the rotating circle 2 to only rotate on its own, and the middle of the cross 9 rotates inside the middle of the supporting table 1, and the middle of the cross 9 is fixedly connected with a return assembly.

[0033] Reference Figure 1 and Figure 3 The return assembly includes a semicircular plate 12, and the semicircular plate 12 allows the cross 9 to rotate horizontally only within a fixed distance. The right end side of the semicircular plate 12 is elastically connected to a fixed block 10 through a spring 2 11. The fixed block 10 is arc-shaped, which can limit the semicircular plate 12 to rotate only at a fixed angle. The semicircular plate 12 is slidably connected to the lower end of the support table 1, and the support table 1 limits the semicircular plate 12 to rotate horizontally only. In this way, the block 6 can slide out of the T-block 13, so that the sliding plate 3 can slide to facilitate the sliding out and sliding in of spare parts. One end of the spring 2 11 is fixedly connected to the right part of the fixed block 10. The squeezing of the spring 2 11 can make the semicircular plate 12 automatically rotate back to its original position, and the other end of the spring 2 11 is fixedly connected to the right side end of the semicircular plate 12.

[0034] Working principle: Select a suitable number of bases 4 according to the needs, so that the connecting block 5 at the side end of the base 4 slides into the inside of the side end of the support table 1, and the lower part of the connecting block 5 squeezes the inclined surface of the inclined surface block 7 so that the inclined surface block 7 can slide into the inside of the support table 1 to squeeze the spring 1 8. When the connecting block 5 slides to the point where it cannot slide anymore, the spring 1 8 squeezes the inclined surface block 7 to slide out to clamp the connecting block 5 and fix it. Place the parts on the support table 1 and clamp them through the clamping device. When the parts need to be replaced, the rotating circle 2 can be rotated, and the rotating circle 2 drives the clamping block 6 and the cross 9 to rotate. The cross 9 drives the semicircular plate 12 to rotate and squeeze the spring 2 11, and the clamping block 6 slides out. When the parts are slid up, the clamping device can drive the sliding plate 3 and the T-block 13 to slide inside the base 4. After the parts are replaced, the T-block 13 slides back to its original position under the magnetic adsorption, and the rotating circle 2 is released. At this time, the spring 2 11 squeezes the semicircular plate 12 back to its original position, so that the cross 9 drives the rotating circle 2 and the clamping block 6 to rotate back to their original positions, so that the T-block 13 is fixed and no longer slides. When the base 4 needs to be disassembled, the inclined plane block 7 can be slid so that the inclined plane block 7 slides into the support table 1 and squeezes the spring 1 8. Then the connecting block 5 is slid horizontally to release the inclined plane block 7, and the spring 1 8 squeezes the inclined plane block 7 back to its original position.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
